Liquidity and spread on british pound cme futures?

I plan to give up trading spot forex to move to currency futures ruled by CME for several reasons : futures are regulated and the cost will lower for me.
I would like to know, if some of you trade the british pound and /or swiss franc futures (during the european day time, that means between 2 to 12 new york time):
1) how much is usually the spread
2) is it liquid enough to trade between 1 and 10 contracts with no problem at all ?

thank you for in answer i think i will move towards futures, less cost, less manipulation and a strong leverage : at IB, the deposit for euro fx is only 1400 $ for contract of 125 000$ , this more leverage that i will ever need
Good trades to every one on ET
